METHOD FOR DISRUPTING COMMUNICATION OF GRAPE VINE MOTH AND EUROPEAN GRAPE BERRY MOTH

摘要

European grapevine moth (GVM) and European grape berry moth (EGBM), which are main pest insects of grapes in Europe, are controlled simultaneously by using a respective sex pheromone substance. Provided is a method for simultaneously controlling GVM and EGBM comprising the steps of incorporating, into a GVM sex pheromone mating disruptant, 5 to 30% by weight of an EGBM sex pheromone component based on an amount of a GVM sex pheromone component in the GVM sex pheromone mating disruptant at the time when in a district A where GVM is a main pest insect, a secondary pest insect EGBM has emerged or is likely to emerge, thereby obtaining a mating disruptant of both GVM and EGBM; or incorporating, into an EGBM sex pheromone mating disruptant, 5 to 35% by weight of a GVM sex pheromone component based on an amount of an EGBM sex pheromone component in the EGBM sex pheromone mating disruptant at the time when in a district B where EGBM is a main pest insect, a secondary pest insect GVM has emerged or is likely to emerge, thereby obtaining a mating disruptant of both GVM and EGBM.
